About install ./utils

[chenyang1999]

Thank you for your great work~
When I try to run your code, I can successfully compile the emd,
but cannot compile the expansion_penalty and MDS and 'Pointnet2.PyTorch':
errors are:

Hi @chenyang1999 , acutally expansion_penalty and MDS are not used in this project as I directly copy the utils folder from VRCNet project. So you need not to compile them. For pointnet2, I am not sure why there is a 'file not found' error as the file should be complete. Maybe you could check the original project https://github.com/sshaoshuai/Pointnet2.PyTorch and try compile from it. Hope this helps.

Thank you very much for your answer, I am a novice in this area, and I will try to compile from the source code ~
If I could solve this problem, I will post my solution to this issue :)
